15. Reduce the printing substrate vacuum under the inkjet print heads.
12.7.7 Problem 5 - Varnish "spreads" at the end of the print as if it had been in contact with something
during printing
12.7.7.1 Explanation
The substrate is pressed against the printing belt. the print heads are at 1.8 mm (new info since June 1 st 2017)
from the substrate. If the latter is not flat. there may be collision between the print heads and the printing substrate.
CAUTION: Print heads are consumables; their price is positively higher than the job to be printed. If the printing
substrate is not flat. it is more judicious to proceed with its printing process than risking damaging one or
more print heads.
12.7.7.2 Solution
16. Check the printing substrate thickness entered in the 3DS Hub Manager; it should correspond to the printing
substrate used.
17. Check that the side vacuum handle corresponds to the printing substrate width.
18. Increase the printing substrate vacuum under the inkjet print heads.
19. Run inkjet printhead wiping.
20. Change printing substrate if the phenomenon persists.
